ADJUSTABLE SUPPORTING-BRACKET.

Specification of Letters Patent.

Patented Dec. 14,1915.

Application filed. March 17, 1915. Seria1N0, 15,145.

justable Supporting-Brackets, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to means for supporting shelves, doors, closures, and like elements, and particularly to supporting means which will support the movable element such as a door, shelf, etc., either in a hori zontal plane or lowered into a vertical plane, and which acts, therefore, in a general way, as a hinge.

T he primary object of my inventionis the I provision of a very simple, cheaply made, and readily applied device of this character,

which is thoroughly effective in action and gives ample support to the movable element when raised.

A further object of my invention is the provision of coacting hinge and supporting members,.one of which is provided with a flat-sided lug and the other with a slot or opening angular in form in which said lug slides upon a movement of the first-named element under proper manipulation.

Otherv objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein:

Figure l is a front view of the upper portion of a range showing the warming chamber of the range and the door or closure for said warming chamber; Fig. 2 is an enlarged secticnal view through the warming chamber of the range shown in Fig. 1, showing my invention applied to the door or closure therefor, the closure or door being in a vertical position; F ig. 3 is a like view, to Fig. 2, but showing the door in its raised or. horizontal position; Fig. 4 is a perspective de- .tailview of the two coacting elements which form one of the hinges, as it may be termed,

for the closure illustrated in Figs. 1 and 2;

Fig. 5 is a sectional view showing my supporting device applied to the shelf.

In Figs. 1, 2, 3 and 4, Ijhave shown my device as applied to supporting the door or closure of the warming chamber of an ordinary range. This is purely illustrativeof one of the applications of my invention, and I do not wish to be limited to this as the towleave a greater clearance space. fore remarked, there are two of these ,sup-

JDOItIng membersB dlSPOS Q Cl O IIG ateach end device may be applied to other constructions without any change in principle.

Referring to Figs. '1, 2, 3 and 4:,A designates a frame adapted to be applied or attached to the rear end of a range, and having the brackets v a which support the usual warming chamber 13. Thedoor or closure for this warming chamber is designated 2, and this door is ordinarily hingedly mounted at its upper end so that the door may swing upward to permit accessto the warming chamber, and means are usually pro vided for supporting this door in a horizontal position. The means ordinarily provided are, relatively speaking, complicated and are not entirelylefi'ective inasmuch as they do not positively lock the door in its raised position, and as .a consequence the door sometimes falls fromthe hand of the user thus interfering with the manipulation of the food disposed in the heating chamber, besides bruising the hands of the operator.

As before stated, the priniary purpose of my invention is to provide means for hingedly supporting th s dcor or closure 2 so that it ,may heraised in avertical plane, and likewise provide means for readily locking this door in'its elevated position, that is, the po- .sitic-n shown in F g. 3. To this end I attach at oppositeends of the chamber l3 supporting elements one of which is illustrated in Fig, 4 and designated 3. This supporting element, when applied to the heating chamber of arange, is provide d with a shank d which is looked or. otherwise attached to the downwardly depending flange 5 of the easing of the warming chamber. The lower or depending end of this shank 4 is enlarged to form a ,head 6, this head having in itthe .substantiallyright angular slot 7. The two arms of this ,slot are disposed at a slightly greater angle than a right angle, as shown most clearly in Fig. ,2, and the metal at the intersection ,of the arms may be cut away, As he ofthe chamber 2. Attached to each end of the closure 2,.which is ordinarily formed of sheet metal, are the supporting strips-Teach having projecting from one 'end thereof the integral lug 10. This lug projects laterally from the supporting ,strip. and ,p eqtsflge- .yond the strip 9 a distance equal to the width of the member 3. Each of the lugs 10 projects into the slot 7 of the correspondtill ing supporting member 3. It will be noted from the drawing that the distance between the lower wall and the upper wall at the the arms of the slot, and thus no binding of the parts on each other can occur. This permits the closure to be readily moved to its raised or lowered position.

The operation of the device will be readily seen from higs. 2 and 3. As before remarked, the slot 1 has two arms or branches, designated in Fig. 4 as 7 and 7". When the door is closed the lugs 10 are disposed in the branch or arm 7 and the door is supported in a depending position. inasmuch as the lug 10 is rectangularin section and has a thickness equal to the depth of the slot 7, it is obvious that the door cannot turn when in its depending position with relation to the supporting members. 111 order to raise the door the door must be pushed upward until the lugs are carried into the upper portion of the slot and then the free end of the door may be raised so as to bring the door into a horizontal position and thedoor is then shoved backward until each lug is carried into the rear end of the slot, that 1s, into the arm 7.

form of the lug,.causing the engagement of the lugs with the walls of the arms 7, will hold the door in its horizontal position. The

door now cannotbe accidentally knocked down or lowered in any manner until the door is drawn forward. When the door is drawn forward so as to carry the lugs 10' illustrated in'l igs. 1 to l, but that it may also be used for supporting shelves or any movable element which is intended to be shifted from a vertical position to a horizon tal position and in a manner locked in either of these positions. Thus, in Fig. 5,1 illustrate my device as applied to the support of a shelf.

In this figure ll designates the shelf and 12 I When this occurs, 'as illustrated in Fig. 3, the rectangular the supporting members, corresponding to the members 3. These supporting members, as illustrated, are each provided with a base 13 which is adapted to be fastened to a wall or other support and with a head 14 which is formed with the angularly disposed slot 15 corresponding to the slot 7 previously described. The shelf 11 is provided adjacent its rear edge and its ends with the outwardly projecting pintle lugs 16. These lugs are arranged in a plane at an angle to the plane of the shelf 11 so that when thelugs 16 are in their rearmost position in the slot 15 the shelf will be supported in a horizontal plane, and that when the shelf is lowered and disposed in a vertical plane the lugs will be parallel to the side walls of the depending arm of each slot. It will be obvious, of course, that the angle of one arm of the slot may be changed relative to the other arm of the slot in order to secure the support of the movable member in a certain predetermined plane, or that the angle of the lug 16 relative to the plane of the movable element may be changed in order to support it in a predetermined angular relation.

The two elements which constitute my improved supporting means may be readily formed by casting though I do not wish to limit myself to this manner of forming these elements.

In practice the device has been found to be very effective and much simpler than.

other supporting means of like character known to me.

Having thus described my invention, what I claim is: r

A locking support of the character described including a member having an at-' taching portion and a head, the head being formed with an angular slot having uni form width, the arms of the slot extending in diverging relation, and a second member coacting therewith having a laterally projecting lug being approximately rectangular in cross section, the lug havinga thickness approximately equalito the width of the slot and a width less than the length of either.

arm of the slot but greater than the width of the slot whereby said second-named member will be held from rotation when disposed entirely in either arm of the slot.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
